Applied through a university recruitment portal.

Passed through two phone-call/Skype interview stages:

• The first was approximately 30 minutes and nontechnical.
• The second was approximately 1 hour and technical.

Invited down to London for an in-person interview (travel expenses reimbursed).

Interviews happened concurrently with approximately 15 others applying for internships/graduate positions.

The first was a 2-hour (or slightly less) technical interview with two engineers. It comprised of whiteboard exercises and a small amount of practical programming on a provided laptop.

This was followed by lunch and a group exercise with 3-4 other applicants (design and market an idea for a travel app).

There was then one final interview with a team leader (fairly nontechnical).

Write a program to accept well-bracketed sequences of characters.

Roughly sketch the high-level design of a vending machine (states/classes/transitions).
